DEVICE'FOR FASTENING ROOFING SHINGLES.

Application filed March 5, 1925. Serial m. 131212.

To all whom it may concern:

Be it known that I. JOHN C. BERGNER, a citizen of the United States, residing at Landsdowne, in-the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Fastening Roofing Shingles, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates generally to devices for fastening shingles, and more especially to a type for retaining the exposed depending or butt ends of diagonally laid shingles against displacement under w1nd pressure, without necessitating the piercing of such ends.

Amongst the objects of my invention are to enable more positive retainment of thebutt ends of the shingles than possible with securing devices heretofore deslgned for this purpose, and to attain this end without any 1 appreciable advance in the cost of production of such devices.

Other subsidiary objects and attendant advantages will become readily apparent from the detailed description which follows of a typical embodiment of my invention;

3 while its scope will be as readily deductible from the appended claims.

In the drawings Fig. I illustrates a fragment of a roof with diagonally placed shingles and the manner in which my improved fastening devices are used; and v Fig. II is a perspective view of one of the fastening devices on a larger scale.

Referrin first to Fig. II of the drawings, it will be 0 served that a shingle fastening device of my invention may, though not necessarily, be conveniently made of a single piece of wire medially bent to afford a loop eral flanks 22. The loop 1 is preferably elongated, as shown, with straight sides 3, 3 convergent toward the regions of mergence with the flanks 22 where they may, if desired, be joined by welding or twisting to insure greater rigidity of the device. The portionsor segments 4, 4 of the lateral flanks 2, 2, it will be noted, extend outwardly from the base of the loop 1 at symmetrical angles relative to the major axis of the latter, to oints 5, 5 somewhat'inward of the loop en where the wire islretroverted to form the segmentsfi, 6 of said flanks. These segments 6, 6 extend rearward of the loop 1 preferably disposed in parallelism as shown, and terminate in perpendicular, downwardly turned prongs 7.7. The prongs 7-7 are sharpened as indicated at 88 so that they may readily be driven into the supporting structure of the roof in a manner which will be presently described.

The securing devices of my invention are applied in roof building as follows:

Either after the laying of a complete course of shingles in diagonal disposal, or the laying of the shingles in such course individually as may be found convenient, one of the devices is employed between each adjacent pair of shingles S as shown in Fig.

depending tips or butt ends incidently en-v gaged. for retainment in the saddle like bights 5-5 of the retroverted flanks 22 and behind the segments 44 of the latter and the loop 1, so that the side edges of each shingle-are thus closely embraced and the exposed areas of the shingles S well anchored. The loops 1 of the securing devices are purposely configured as shown so as to practically cover the whole of that portion;

of the shingle tip which overhangs the crotch of the angle formed between the overlapped shingles S. of a subjacent course, it being this portion of the shingle, by reason of the interspace existing beneath it, vghich ismost liable to be lifted by the Wll'l It is to be particularly noted that the disposal of the segments 44 ofthe flanks 2-, 2

is so ordered that they occupy a perpendicular position relative to the'sideedges of the shingle and thereby function in an auxiliary capacity to the loop 1; and furthermore, that the retroverted portions or segments 6 of the flanks 2 bear, throughout their lengths, against the shin les course and there ore assist in more effectively securing the latter to the supporting structure of the roof.

The fastening devices of my invention- S of a subjacentmay of course be employed in securing strip shingles simulating the result ultimately procured by laying of individual shingles. The method of procedure is thought to be so obvious from what has already been stated as to preclude the necessity for .repetitive description.

Having thus described my invention, I claim:

1. A shingle fastening device formed of a single lengthv of Wire to afford an elongated loop having lateral flanks, said loops and flanks being adapted to grip the exposed butt end of a diagonally placed shingle, and incorporated securing means capable of being concealed beneath the shingle.

2-. .A shingle fastening device formed of a single piece of wire bent to provide a closed elongated vertical loop adapted to grip the butt end of a diagonally placed shingle, and lateral flanks extending angularly outward from the base of the loop at a perpendicular to the side edges of the shingle, said flanks llavingportions' retroverted to embrace the side edges of a shingle, the latterportions being disposed substantially parallel with the major axis of the loop and formed with securing ends capable of being concealed beneath the shingle.

3. A shingle fastening device formed of a single piece of wire bent to provide a closed elongated vertical loop adapted to overlie the butt end of a diagonallyplaced shingle, and lateral flanks comprising segments extending angularly outward from the base of the loop at a erpendicular to the side edges,

of the shing e, and segments retroverted relative to the first so that the side edges of the shingles aforesaid may be embraced, the latter segments being disposed substantially in parallelism with the major axis of the loop and formed with securing means capable of being concealed beneath the shingle.

4. A shingle fastening device'formed of a single piece of wire bent to provide a closed elongated vertical loop adapted to overlie the butt end of a diagonally placed shingle, and lateral flanks comprising segments extending angularly outward from the base of the loop at a perpendicular to the side edges of the shingle, and segments retroverted relative to the first so that the side edges of the shingles aforesaid may be embraced, the latter segments being disposed substantially in parallelism with the major axis of the loop and terminating in downturned sharpened securing prongs.

5. As a new article of manufacture, a

shingle fastening device fabricated from a single length of wire to provide .a closed elongated loop having lateral angular flanks embodying securing portlons retroverted 1nto substantial parallelism with the major axis of the loop aforesaid.

(5. As a new article of manufacture, a shingle fastening device fabricated from a single length of wire to provide a closed elongated lcop with lateral angular flanks having portions retroverted into substantial parallelism with the major axis of the loop, said retroverted portions terminating in angularly turned securing prongs.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 2nd. day of March 1925.

JOHN C. BERGNER.
